Mapstone YR 1976 UL http://bjo.bmj.com/content/60/2/115.abstract AB Altogether 119 eyes at risk of developing closed-angle glaucoma were provoked with simultaneous pilocarpine and phenylephrine; of these 74 developed closed-angle glaucoma. The remaining 45 eyes were re-provoked with tropicamide and a further nine developed closed-angle glaucoma. The 36 eyes in which all tests were negative were given no treatment and have been observed for a period of 1 to 7 years (mean 3 years). One has developed closed-angle glaucoma. A scheme for provoking eyes at risk of developing closed-angle glaucoma is described.
